[11.04] Formation of Substellar Objects: A SIRTF Legacy

SIRTF observations for the Legacy Project, From Molecular
Cores to Planet-Forming Disks, will include over 20 square
degrees in five molecular clouds and maps of 135 isolated
star-forming cores in the mid- to far-infrared wavelengths.
The Legacy data will also include ancillary millimeter
observations of these regions.

We present a summary of the Legacy observations with
coverage and sensitivities---a multi-wavelength database
incorporating numerous methods of observation---along with
estimated background star and galaxy counts. In addition, we
review criteria for the selection of young, substellar
objects, in particular, from the vast database provided by
the SIRTF Legacy team. Finally, based on the previous
detections of brown dwarfs in the optical and near-infrared
and theoretical models, we estimate the number of brown
dwarfs to be revealed by these observations.
